Answer 1

The equation of the tangent line to the curve at the point (x1,y1) is

  y - y1 = - 3.54(x - x1)

What is a tangent?

The straight line that just touches the curve at a given location is referred to as the tangent line to a plane curve in geometry.

Given parametric equations,

x(t)=sin(8t)

y(t)=−8cos(−5t)

We now differentiate the above equations with respect to t.

dx/dt = 8cos(8t)

dy/dt = -8 * -5 * -sin(-5t) = -40sin(-5t)

the slope of tangent =  dy/dx of the curve.

dy/dx = (dy/dt)/(dx/dt) = -40sin(-5t) / 8cos(8t) = -5[ sin(-5t)/cos(8t) ]

Equation of a tangent to the curve

y - y1 = dy/dx (x-x1)

When t = (3π/4)

dy/dx = -5[ sin(-5*3π/4) / cos(8* 3π/4) ] = -5[ 0.707/1] = - 3.54

Therefore the equation of the tangent line at point (x1,y1) is

  y - y1 = - 3.54(x - x1)

Answers

The probability of a random patient being alcoholic with elevated cholesterol levels is 55/80, or 0.6875. The probability of a random patient being nonalcoholic is 320/400, or 0.8. Lastly, the probability of a random patient being nonalcoholic with Non elevated cholesterol levels is 248/400, or 0.62.

To calculate the probability of a random patient being alcoholic with elevated cholesterol levels, we must first determine the total number of patients with elevated cholesterol levels. This can be done by adding the number of alcoholic patients (55) with elevated cholesterol levels to the number of nonalcoholic patients (72) with elevated cholesterol levels.

The result is a total of 127 patients with elevated cholesterol levels. This means that out of 400 patients, 55 of them were alcoholic and had elevated cholesterol levels. Therefore, the probability of a random patient being alcoholic with elevated cholesterol levels is 55/400, or 0.6875.

The probability of a random patient being nonalcoholic is equal to the total number of nonalcoholic patients (320) divided by the total number of patients (400). This yields a probability of 0.8.

Answers

The total amount to be paid back would be $35,731.73.

What is the amount ?

The amount is 100 words. Plagiarism is not allowed, so the answer must be original and unique.The amount is unspecified and cannot be determined without further information.

This can be calculated using the formula for compound interest:

A = P(1 + r/n)^nt,

where A is the total amount to be paid back, P is the principal amount (31,000), r is the annual interest rate (3%), n is the number of times the interest is compounded per year (annually in this case), and t is the number of years (11).

Plugging this into the formula, we get:

A = 31000 (1 + 0.03/1)^11

A = 31000 (1.03^11)

A = 31000 (1.357364)

For the given figure, the value of different angles, x = 122° and w = 90°.

An angle is a shape in planar geometry made up of two rays or lines that have a common termination. The Latin word "angulus," which meaning "corner," is where the English term "angle" originates. The shared termini of two rays are the vertex and the two rays, which are referred to as the sides of an angle, respectively. When two rays meet at a point, they create an angle. The "angle," which is the term used to describe the "opening" between these two rays, is represented by the symbol. Angles are typically expressed as 60°, 90°, etc. and are measured in degrees.

For the given figure,

The value of angle w is 90°.

As per the quadratic equation, the value of k is 48 ± 8√26.

The term called quadratic equation is known as the polynomial equation whose highest degree is two

Here we know that the value of the quadratic equation is written as,

=> (k - 4)x² - 3kx - 4(k -2) = 0.

Here we have identified that the given equation is in the form of ax² + bx + c = 0.

Then the value of a = k - 4, b = -3k and c = 4(k-2)

Now, we have to use the quadratic formula to identify the value of k, then it can be written as.

=> (-3k)² - (4 x (k - 4) x 4(k-2))

=> 9k² - ((4k - 16) x (4k - 8))

Answers

We can start by taking a look at the first equation. We can move -5y to the other side with 16, to get x = 5y + 16.

Multiply both each term by 4 in this equation to get this:
4x = 20y + 64

Keep this aside for now; you will need it later.

Now, look at the second equation. Move -2y to the other side of the equation so that it is with -8. The equation will now look like this:
4x = 2y - 8

Now, go back to the first equation where we just multiplied by 4; take 20y + 64 and set it equal to 2y - 8. It should look like this:
20y + 64 = 2y - 8

Simplify:
18y = -72
y = -4

Now that we found y, substitute -4 for y in one of the given equations (I chose the first one):

The distance from the center point to a corner flag is approximately 6.4 cm on the plan

The length and width of the rectangular field, on a scale of 1 cm to 10 m, can be represented as 104 m / 10 = 10.4 cm and 76 m / 10 = 7.6 cm, respectively. The half of the length is 5.2 cm and the half of the width is 3.8 cm.

To find the distance from the center point to a corner flag, we need to use the Pythagorean theorem. The distance is the square root of the sum of the squares of half the length and half the width:

√(5.2^2 + 3.8^2) = √(27.04 + 14.44) = √41.48

y=-1/4x-2 is the  equation of the line that is perpendicular to y = 4x + 6 and passes through the point (8, −4).

What is Slope of Line?

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

The slope of perpendicular line will be -1/m

In the equation  y = 4x + 6  the slope m is 4

The slope of perpendicular line will be -1/4

Now let us find the y intercept

-4=-1/4(8)+b

-4=-2+b

-2=b

y=-1/4x-2 is the equation of perpendicular line.

In an equation such as the quadratic equation, cubic equation, etc., a polynomial function is a function that only uses non-negative integer powers or only positive integer exponents of a variable. For instance, the polynomial 2x+5 has an exponent of 1.

For the given factors, write the factors in the coefficient form, following form:

a, (a - 5), (a + 5 - √8)

At Pharoah’s Palace, a hypothetical Las Vegas casino, management has tampered with the dice. Management modified a standard six-sided die so that the probability of each side is now proportional to the number of spots on the side.

Calculate the mean of the uncertainty distribution.

Calculate the standard deviation of the uncertainty distribution.

Suppose that you know all about the casino’s tampering with the dice. Now the casino offers to pay you $1,000 for each spot showing on the up side of a single throw of the die. But the casino will charge you $4,000 for the right to play the game. Would you accept the casino’s offer to play? Why or why not?

The probability distribution of a random event describes the likelihood of each possible outcome of that event.

In the case of the modified die at Pharaoh's Palace, the management has changed the standard probability distribution so that the probability of each side is proportional to the number of spots on the side.

The possible outcomes are 1, 2, 3, 4, 5, and 6, and their probabilities can be calculated by summing up the probabilities of each side and ensuring that they add up to 1.

The mean of the uncertainty distribution is calculated by taking the sum of each possible outcome multiplied by its probability and dividing by the number of possible outcomes.

At a price of $44, 30 units of good x are exchanged. This can be calculated by subtracting the quantity supplied at price $15 (q0=10) and the quantity supplied at price $31 (q*=30) from the quantity demanded at price $44 (q1=50).

At a price of $44, the quantity of good x that is exchanged can be calculated by subtracting the quantity supplied at price $15 (q0=10) and the quantity supplied at price $31 (q*=30) from the quantity demanded at price $44 (q1=50). The quantity supplied at price $15 is 10 units, the quantity supplied at price $31 is 30 units, and the quantity demanded at price $44 is 50 units. Therefore, the quantity exchanged at price $44 is 50 units minus 10 units (q0) minus 30 units (q*) which equals 10 units. Thus, the quantity of good x exchanged at price $44 is 10 units.

What is the percentage increase from 520 to 800

Answers

The percentage increase from 520 to 800 is 53.85%

solve for u please: u-5/9=5/6

Answers

To solve the equation u - 5/9 = 5/6, you can use the following steps:

Start by adding 5/9 to both sides of the equation:
u - 5/9 + 5/9 = 5/6 + 5/9
Simplifying the left side of the equation:
u = 5/6 + 5/9
Simplifying the right side of the equation:
u = (5/6 + 5/9)
u = (30 + 45) / 54
u = 75 / 54
Simplifying the fraction:
u = 5/4
Therefore, the solution to the equation is u = 5/4

An equation of the secant line containing and (-7,g(-7)) and (8,g(8)) is

Answers

The equation of the secant line containing the points (-7,g(-7)) and (8,g(8)) is y = (123/15)x + (98 - (123/15) * (-7)).

How did we get the values?

The equation of a line in slope-intercept form is y = mx + b, where m is the slope of the line and b is the y-intercept. To find the equation of the secant line, we need to find the slope (m) and the point of intersection (x,y) of the line with the y-axis.

To find the slope (m) of the secant line, we can use the formula:

m = (y2 - y1) / (x2 - x1)

where (x1,y1) = (-7, g(-7)) and (x2,y2) = (8, g(8)).

So, m = (g(8) - g(-7)) / (8 - (-7)) = (g(8) - g(-7)) / 15

Now, we can substitute the value of g(x) in the above equation and get the value of m

g(x) = 2x^2-7

m = (2(8^2)-7 - 2(-7^2)-7) / 15 = (2(64)-7 - 2(49)-7) / 15 = (128-7-98-7) / 15 = 123/15.

To find the point of intersection (x,y) of the line with the y-axis, we can use one of the given points and the slope. Let's use the point (-7,g(-7))

y = mx + b

g(-7) = m * (-7) + b

b = g(-7) - m * (-7)

We can substitute the value of g(x), m and x = -7 in the above equation and get the value of b.

g(x) = 2x^2-7

b = 2(-7)^2-7 - m * (-7) = 2(49)-7 - 123/15 * (-7) = 98 - 123/15 * (-7)

So, the equation of the secant line containing the points (-7,g(-7)) and (8,g(8)) is y = (123/15)x + (98 - (123/15) * (-7))

find the change in the density rho of a substance, when the temperature changes by δt . assume βδt≪1 .

Answers

The change in the density rho of a substance when the temperature changes by δt is dρ = -β × δt × ρ.

The change in density, dρ, of a substance when the temperature changes by delta_t (δt) can be calculated using the coefficient of thermal expansion, beta (β):

dρ = -β × δt × ρ

Where rho is the original density of the substance. If beta * delta_t is much less than 1 (beta * delta_t << 1), then the change in density can be considered to be small, and the original density can be used in the calculation.

Therefore, the change in density rho is -β × δt × ρ.

when you calculate the number of combinations of r objects taken from a group of n objects what are you counting? give an example.

Answers

Answer:

Below

Step-by-step explanation:

You are counting the number of SUBSETS

Example  set  {2,7}

  has subsets { }   {2}  {7}  {2,7}

The number of subsets given a set of 'n'  is   2^n

When you calculate the number of combinations of "r" objects taken from a group of "n" objects, you are counting the number of different ways you can choose "r" items from the "n" items without regard to their order (i.e. their arrangement does not matter).

What is combination?

A combination in mathematics is a selection of elements from a set with distinct members, where the order of selection is irrelevant. A combination is a method of picking elements from a collection when the order of selection is irrelevant. Assume we have three integers P, Q, and R. Combination defines how many possibilities we may choose two numbers from each set. A combination is a mathematical approach for determining the number of potential arrangements in a set of objects when the order of the selection is irrelevant. You can choose the components in any order in combinations. For example, if you have a group of 6 books and you want to know how many different combinations of 3 books you can choose, you would use the formula: C(6,3) = 6!/(3! * (6-3)!). The answer would be 20, meaning there are 20 different combinations of 3 books you can choose from the group of 6.
